Loving cold weather is easy in the right gear! This super warm jacket is designed to direct body heat back to your core using in built, ultra-light Reflect technology – which keeps you up to 20% warmer* than you would be without it. While the Hydrodown® filling, made up of RDS certified down treated with Nikwax®, is able to keep you warm all day long, even in wet conditions.

To reduce the bulk, areas of lightweight Pertex® Quantum on the outside are windproof and bring easy movement to strenuous hikes. This paired with stretch fleece panels under the arms and sides creates a performance fit. So there’ll be no stopping you on your next freezing challenge.

This high-performance jacket offers unrivaled warmth without unnecessary bulk or weight. Its HydroDown duck down core is wrapped in windproof Pertex Quantum fabric, meaning you will remain warmer for longer, even in damp conditions.

Feature wise, there's 2 large hand warmer pockets, an elastic bound hood (no adjustments) and stretchy fleece cuffs made from the same stretchy fleece on the sides of the jacket.

The new Tephra Stretch jacket uses "Reflect" technology which is a metallic mesh fabric that boosts body temperature by up to 20% versus the same jacket without the "Reflect" mesh. We've seen foil work elsewhere in outdoor gear to provide extra warmth so it seems like a good idea to stick it in a jacket.
